source("script_region.R")Description The Habitat Compression Index (HCI) is the area of cool habitat along the coast, which is suitable for a diverse and productive portion of the CCE food web. HCI is estimated in four biogeographic provinces along the shelf within the CCE.

Public availability statement Source data are publicly available.
Data sources Surface temperature data are the 2 m temperature levels of the University of California Santa Cruz 31-year historical reanalysis (https://oceanmodeling.ucsc.edu/reanalccs31/) and near-real-time (NRT; https://oceanmodeling.ucsc.edu/ccsnrt/) data-assimilative models.
Additional Information The HCI is defined over 4 regions along the coast (43.5-48°N, 40-43.5°N, 35.5-40°N, and 30-35.5°N). The HCI is calculated the same for each region and is defined as the area of cool monthly averaged sea temperatures at a depth of 2 m that fall below a temperature threshold, in a region extending from the coast to 150 km offshore between the latitude ranges of the 4 regions. Each month has a unique temperature threshold that is defined as the spatial average of all 2 m temperatures from the coast to 75 km offshore in the latitudinal region for a given month over a climatological period of 1980 to 2010 Schroeder et al. (2022).
